Perhaps they could start to study magic together early. Hermione, being the studious type, might share some basic magic knowledge she has learned from books with Harry. They could practice simple spells in secret, away from Muggles. This would give Harry a head start in his magical education and also make their relationship more unique compared to what we see in the original series.
They might become fast friends. In some fanfictions, they could discover their shared love for magic books even before Hogwarts. This early encounter could lead to them sharing secrets about their strange magical experiences prior to school, like Hermione telling Harry about her accidental magic incidents and Harry sharing his strange encounters with the Dursleys. This would strengthen their bond and perhaps make their Hogwarts years even more intertwined.
It's possible that they would form a plan to deal with the challenges of Hogwarts before they even get there. For example, they might decide to work together to find out more about Voldemort's past if they somehow got a hint of the danger that was to come. This would set them on a different path of adventure and discovery even before they step foot in Hogwarts.
Well, they might become friends. Maybe they discover they have a shared interest in magic even before getting to Hogwarts. For example, they could both be fascinated by magical creatures and exchange stories about the ones they've read about.
In some fanfictions, they might initially dislike each other. Draco, with his pure - blood supremacist upbringing, could look down on Harry. For example, he might make snide remarks about Harry's lack of knowledge about the wizarding world. However, this early encounter could also lead to a different dynamic later at Hogwarts. Maybe Harry would be more prepared to face Draco's taunts because of this prior meeting.
In such a fanfiction scenario, it could be quite emotional. Harry might finally get to know his parents in a more personal way. He could have conversations with them, learn about their lives before he was born, and perhaps gain a deeper understanding of his family's history. Hermione, on the other hand, could act as a sort of mediator or observer, helping Harry through this extraordinary encounter.
Well, they might discover their shared love for magic right away. Maybe they find some strange magical creature together and start to figure out how to take care of it. This could be a start of their magical adventures even before Hogwarts.
I really liked the fanfiction where Harry and Hermione go on a quest to find a lost magical artifact that was once owned by one of the Hogwarts founders. It was a great story that showed their determination and loyalty to each other and to Hogwarts.
Well, in many fanfictions, Hermione's parents might be initially a bit surprised by Ron and Harry's wizarding world ways. They could be impressed by their magical skills. Maybe Ron would make them laugh with his goofy charm, and Harry would seem very polite and brave to them.
In this type of fanfiction, if Hermione is adopted by the Hogwarts staff, she could gain a different level of access to the school's resources. For example, if she was adopted by Flitwick, the Charms professor, she might have unlimited access to the Charms classroom to practice and experiment. This would make her even more proficient in Charms than she already is in the original story. And she could develop new spells or improve existing ones.
In the fanfiction, there could be a mystery at Hogwarts that brings them back together. For example, a dark magic artifact that was hidden long ago resurfaces. Draco, with his Slytherin knowledge of the castle's secrets, and Hermione, with her vast research skills, team up to solve the mystery. Along the way, they discover new things about each other and themselves, and perhaps even develop some romantic feelings, though it would be a very unexpected and complex relationship given their past.
Well, in some fanfics, they could face some challenges when they meet again. There might be misunderstandings or outside forces trying to keep them apart. But in the end, their love for each other would prevail. They might have a big, emotional reunion where they realize how much they've missed one another and vow to never be apart for too long again.
One great fanfiction could be about Harry and Hermione's adventures in the Forbidden Forest. They might discover a new magical creature that was thought to be extinct. Their friendship would be tested as they try to protect the creature from those who would want to use it for dark magic.
